Description

FIELD OF THE INVENTION
This invention relates to late transition metal catalysts for olefin oligomerization or polymerization and to methods for making and using these catalysts.
BACKGROUND OF THE INVENTION
Olefins, especially those containing 6 to 20 carbon atoms, are important items of commerce. They are used as intermediates in the manufacture of detergents, as monomers (especially in linear low-density polyethylene), and as intermediates for many other types of products. Consequently, improved methods of making these compounds are desired. Especially desired, is a process capable of making a range of linear and branched olefins such as butene, hexene, octene and even higher olefins since as octadecene.
Most commercially produced alpha-olefins are made by the oligomerization of ethylene, catalyzed by various types of compounds, see for instance B. Elvers, et al., Ed. Ullmann's Encyclopedia of Industrial Chemistry, Vol. A13, VCH Verlagsgesellschaft mbH, Weinheim, 1989, p. 243–247 and 275–276, and B. Cornils, et al., Ed., Applied Homogeneous Catalysis with Organometallic Compounds, A Comprehensive Handbook, Vol. 1, VCH Verlagsgesellschaft mbH, Weinheim, 1996, p. 245–258. The major types of commercially used catalysts are alkylaluminum compounds, certain nickel-phosphine complexes, and a titanium halide with a Lewis acid such as AlCl3. In all of these processes, significant amounts of branched internal olefins and diolefins are produced. Since in most instances these are undesirable and often difficult to separate, these byproducts are avoided commercially.
More recently, some iron complexes bearing tridentate chelating bis(imino)pyridine ligands when activated have been reported to produce oligomers (B. L. Small and M. Brookhart, J. Am. Chem. Soc. 1998, 120, 7143; M. Brookhart and B. L. Small, PCT Int. Appl. WO9902472, 1999 (DuPont)). Imino-bipyridine based iron complexes when activated produce low molecular weight oligomers (G. J. P. Britovsek, S. D. Baugh, O. Hoarau, V. C. Gibson, D. F. Wass, A. J. P. White, D. J. Williams, Inorg. Chim. Acta 2003, 345, 279. Bis(hydrazone)pyridine complexes of iron afford mixtures of low molecular weight polymer and oligomers (G. J. P. Britovsek, V. C. Gibson, B. S. Kimberley, S. Mastroianni, C. Redshaw, G. A. Solan, A. J. P. White, D. J. Williams, J. Chem. Soc., Dalton Trans. 2001, 1639; M. O. Kristen, A. Gonioukh, D. Lilge, S. Lehmann, B. Bildstein, C. Amort, M. Malaun PCT Int. Appl. WO0114391, 2001 (BASF); L. S. Moody, P. B. MacKenzie, C. M. Killian, G. G. Lavoie, J. A. Ponasik Jr., T. W. Smith, J. C. Pearson, A. G. M. Barrett, G. W. Coates, PCT Int. Appl. WO0183571, 2001 (Eastman); L. S. Moody, P. B. MacKenzie, C. M. Killian, G. G. Lavoie, J. A. Ponasik Jr., A. G. M. Barrett, T. W. Smith, J. C. Pearson, PCT Int. Appl. WO0050470, 2000 (Eastman)). Iron based oligomerization catalysts have been reported in G. J P. Britovsek, S. Mastroianni, G. A. Solan, S. P. D. Baugh, C. Redshaw, V. C. Gibson, A. J. P. White, D. J. Williams and M. Elsegood, Chem. Eur. J., 2000, 6, 221, and in G. J. Britovsek, B. Dorer, V. C. Gibson, B. S. Kimberley and G. A. Solan, WO9912981, 1999 (BP Chemicals Ltd.).
Hence new oligomerization catalysts are of great interest in the industry because they offer many new opportunities for providing new processes and products to the markets in a cheaper and more efficient manner. The following invention relates to new oligomerization technology based upon new late transition metal catalyst compounds.

 DEFINITIONS
As used herein, the new numbering scheme for the Periodic Table Groups are used as in CHEMICAL AND ENGINEERING NEWS, 63(5), 27 (1985).
For the purposes of this invention and the claims thereto and for ease of reference when a polymer is referred to as comprising an olefin, the olefin present in the polymer is the polymerized form of the olefin. Likewise when catalyst components are described as comprising neutral stable forms of the components, it is well understood by one of ordinary skill in the art, that the ionic form of the component is the form that reacts with the monomers to produce polymers. In the description herein the transition metal catalyst compound may be described as a catalyst precursor, a pre-catalyst compound or a catalyst compound, and these terms are used interchangeably. A catalyst system is a combination of a transition metal catalyst compound and an activator. An activator is also interchangeably referred to as a cocatalyst.
The term “hydrocarbyl radical” is sometimes used interchangeably with “hydrocarbyl” throughout this document. For purposes of this disclosure, “hydrocarbyl radical” encompasses C1–C50 radicals. These radicals can be linear, branched, or cyclic including polycyclic. These radicals can be saturated, partially unsaturated or fully unsaturated, and when cyclic, may be aromatic or non-aromatic.
In describing a ligand, a terminal nitrogen atom, is a nitrogen atom that is indirectly bonded to only one other nitrogen atom. A central nitrogen atom is a nitrogen atom that is indirectly bonded to two or more other nitrogen atoms. An example is illustrated below:
Figure US07189791-20070313-C00002
Substituted hydrocarbyl radicals are radicals in which at least one hydrogen atom has been replaced with a heteroatom or with at least one functional group such as NR″2, OR″, PR″2, SR″, BR″2, SiR″3, GeR″3 and the like or where at least one non-hydrocarbon atom or group has been inserted within the hydrocarbyl radical, such as O, S, NR″, PR″, BR″, SiR″2, GeR″2, and the like, where R″ is independently a hydrocarbyl or halocarbyl radical. The functional group can be an organometalloid radical.
Halocarbyl radicals are radicals in which one or more hydrocarbyl hydrogen atoms have been substituted with at least one halogen or halogen-containing group (e.g. F, Cl, Br, I).
Substituted halocarbyl radicals are radicals in which at least one hydrocarbyl hydrogen or halogen atom has been substituted with at least one functional group such as NR″2, OR″, PR″2, SR″, BR″2, SiR″3, GeR″3 and the like or where at least one non-carbon atom or group has been inserted within the halocarbyl radical such as O, S, NR″, PR″, BR″, SiR″2, GeR″2, and the like where R″ is independently a hydrocarbyl or halocarbyl radical provided that at least one halogen atom remains on the original halocarbyl radical. The functional group can be an organometalloid radical.
In some embodiments, the hydrocarbyl radical is independently selected from methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, octadecyl, nonadecyl, eicosyl, heneicosyl, docosyl, tricosyl, tetracosyl, pentacosyl, hexacosyl, heptacosyl, octacosyl, nonacosyl, triacontyl, ethenyl, propenyl, butenyl, pentenyl, hexenyl, heptenyl, octenyl, nonenyl, decenyl, undecenyl, dodecenyl, tridecenyl, tetradecenyl, pentadecenyl, hexadecenyl, heptadecenyl, octadecenyl, nonadecenyl, eicosenyl, heneicosenyl, docosenyl, tricosenyl, tetracosenyl, pentacosenyl, hexacosenyl, heptacosenyl, octacosenyl, nonacosenyl, triacontenyl, propynyl, butynyl, pentynyl, hexynyl, heptynyl, octynyl, nonynyl, decynyl, undecynyl, dodecynyl, tridecynyl, tetradecynyl, pentadecynyl, hexadecynyl, heptadecynyl, octadecynyl, nonadecynyl, eicosynyl, heneicosynyl, docosynyl, tricosynyl, tetracosynyl, pentacosynyl, hexacosynyl, heptacosynyl, octacosynyl, nonacosynyl, or triacontynyl isomers. For this disclosure, when a radical is listed it indicates that radical type and all other radicals formed when that radical type is subjected to the substitutions defined above. Alkyl, alkenyl and alkynyl radicals listed include all isomers including where appropriate cyclic isomers, for example, butyl includes n-butyl, 2-methylpropyl, 1-methylpropyl, tert-butyl, and cyclobutyl (and analogous substituted cyclopropyls); pentyl includes n-pentyl, cyclopentyl, 1-methylbutyl, 2-methylbutyl, 3-methylbutyl, 1-ethylpropyl, and neopentyl (and analogous substituted cyclobutyls and cyclopropyls); butenyl includes E and Z forms of 1-butenyl, 2-butenyl, 3-butenyl, 1-methyl-1-propenyl, 1-methyl-2-propenyl, 2-methyl-1-propenyl and 2-methyl-2-propenyl (and cyclobutenyls and cyclopropenyls). Cyclic compound having substitutions include all isomer forms, for example, methylphenyl would include ortho-methylphenyl, meta-methylphenyl and para-methylphenyl; dimethylphenyl would include 2,3-dimethylphenyl, 2,4-dimethylphenyl, 2,5-dimethylphenyl, 2,6-diphenylmethyl, 3,4-dimethylphenyl, and 3,5-dimethylphenyl.
For purposes of this disclosure, the term oligomer refers to compositions having 2–75 mer units and the term polymer refers to compositions having 76 or more mer units. A mer is defined as a unit of an oligomer or polymer that originally corresponded to the olefin(s) used in the oligomerization or polymerization reaction. For example, the mer of polyethylene would be ethylene.
Anionic monodentate ligands, also called abstractable ligands, are ligands that are removed from the catalyst precursor to activate it. They are sometimes assigned the label X in this disclosure. X are independently hydride radicals, hydrocarbyl radicals, or hydrocarbyl-substituted organometalloid radicals; or two X's are connected and form a 3-to-50-atom metallacycle ring. Specifically, this metallacycle ring could take the form of a bidentate dianionic ligand.
When Lewis-acid activators such as methylalumoxane, aluminum alkyls, alkylaluminum alkoxides or alkylaluminum halides that are capable of donating an X ligand, as described above, to the transition metal component are used, or when the ionic activator is capable of extracting X, one or more X, which may optionally be bridged to one another, may additionally be independently selected from a halogen, alkoxide, aryloxide, amide, phosphide or other anionic ligand, provided that the resulting activated catalyst contains as least one M-H or M-C connection in which an olefin can insert.
When the pre-catalysts of this invention are drawn as dimeric species, two X may be independently a mono-anionic bridging ligand that is bonded to each M (e.g. μ-X).
In some structures throughout this specification the ligand-metal connection is drawn with an arrow indicating that the electrons originally came from the ligand. At other times, the connection is shown by drawing a solid or dashed line. One of ordinary skill in the art recognizes that these depictions are interchangeable.
Alicyclic rings are aliphatic radicals that have a ring or cyclic structure in which the ring portion may be saturated or unsaturated, but in which the ring portion may not be aromatic. One of ordinary skill in the art recognizes that alicyclic, as defined in this document, is a subset of hydrocarbyl, as defined in this document.

Transition metal complexes of this invention are typically prepared by reacting the tridentate or tetradentate ligand, L, with the desired metal halide, preferably a metal dihalide, in an appropriate solvent, preferably n-butanol, and heating the reaction mixture.
Invention catalyst systems can additionally be prepared by combining, in any order, the ligand, with a Group 7, 8, 9, 10 or 11 metal halide salt, which may optionally be coordinated by solvent, in an activator solution (for example, methylalumoxane dissolved in toluene). All reactants may be added in any order, or even essentially simultaneously.
Common activators that are useful with this invention include:
  • 1. Alumoxanes including alkyl alumoxanes and modified alkylalumoxanes, such as methylalumoxane, modified methylalumoxane, ethylalumoxane and the like;
  • 2. Aluminum alkyls such as trimethyl aluminum, triethyl aluminum, triisopropyl aluminum and the like, and alkyl aluminum halides such as diethyl aluminum chloride, and including alkylaluminum alkoxides; and
  • 3. Ionizing or stoichiometric activators.
The alumoxane component useful as an activator typically is an oligomeric aluminum compound represented by the general formula (R″—Al—O)n, which is a cyclic compound, or R″(R″—Al—O)nAlR″2, which is a linear compound. In the general alumoxane formula, each R″ is independently a C1–C20 alkyl radical, for example, methyl, ethyl, propyl, butyl, pentyl, isomers thereof, and the like, and “n” is an integer from 1–50. Most preferably, R″ is methyl and “n” is at least 4. Methylalumoxane and/or modified methylalumoxanes are most preferred. Another preferred alumoxane is a modified methyl alumoxane (MMAO) cocatalyst type 3A (commercially available from Akzo Chemicals, Inc. under the trade name Modified Methylalumoxane type 3A, covered under patent number U.S. Pat. No. 5,041,584). For further descriptions see, EP 279586, EP 561476, WO94/10180 and U.S. Pat. Nos. 4,665,208, 4,908,463, 4,924,018, 4,952,540, 4,968,827, 5,041,584, 5,103,031, 5,157,137, 5,235,081, 5,248,801, 5,329,032, 5,391,793, and 5,416,229.
Aluminum alkyl components useful as an activators are represented by the general formula:
Rm′″AlZP
  • where each R′″ is, independently, a C1–C20 alkyl radical, for example, methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, and isomers thereof, preferably methyl, ethyl, propyl, butyl, isobutyl, hexyl, octyl, more preferably methyl, ethyl, isobutyl, n-hexyl or n-octyl;
  • m is 1, 2 or 3;
  • each Z is, independently, a C1–C20 alkyl radical, for example, methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, and isomers thereof, preferably methyl, ethyl, propyl, butyl, isobutyl, hexyl, octyl, or n-octyl, each Z may also be a different univalent anionic ligand such as a halogen (preferably Cl, Br, I), or an alkoxide (OR*), where R* is a C1–C20 alkyl radical, for example, methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, and isomers thereof, preferably methyl, ethyl, propyl, butyl, isobutyl, hexyl, octyl, or n-octyl, preferably R* is preferably methyl, ethyl, propyl, butyl, isobutyl, hexyl, octyl, n-octyl, chloro, methoxide, ethoxide, propoxide, isopropoxide, butoxide, or t-butoxide; and
  • p is 0, 1 or 2. Preferred aluminum alkyl compounds which may be utilized as activators (or scavengers) include triethylaluminum, diethylaluminum chloride, triisobutylaluminum, tri-n-octylaluminum, trimethylaluminum, and tri-n-hexylaluminum.
When alumoxane, or aluminum alkyl activators are used, the catalyst-precursor-to-activator molar ratio is from about 1:2000 to 10:1; alternatively, 1:1200 to 1:1; alternatively, 1:1000 to 1:1; alternatively 1:500 to 1:1; alternatively 1:400 to 1:10, or alternatively 1:300 to 1:10.
Ionizing activators may be used in the practice of this invention. Preferably, discrete ionizing activators (sometimes also referred to as ionic activators) such as [Me2PhNH][B(C6F5)4], [Bu3NH][BF4], [NH4][PF6], [NH4][SbF6], [NH4][AsF6], [NH4][B(C6H5)4] or Lewis acidic activators such as B(C6F5)3 or B(C6H5)3 can be used if they are used in conjunction with a compound capable of alkylating the metal such as an alumoxane or aluminum alkyl, or if in the pre-catalyst, X is a hydride, hydrocarbyl, substituted hydrocarbyl, halocarbyl, substituted halocarbyl. For purposes of this invention and the claims thereto, Ph is phenyl, Bu is butyl, C6H5 is phenyl; C6F5 is perfluorophenyl or pentafluorophenyl.
It is within the scope of this invention to use an ionizing or stoichiometric activator, neutral or ionic, such as tri(n-butyl)ammonium tetrakis(pentafluorophenyl)boron, a tris(perfluorophenyl)boron metalloid precursor or a tris(perfluoronaphthyl)boron metalloid precursor, polyhalogenated heteroborane anions (WO 98/43983), boric acid (U.S. Pat. No. 5,942,459) or combination thereof. It is also within the scope of this invention to use neutral or ionizing activators alone or in combination with alumoxane or modified alumoxane activators.
Examples of neutral stoichiometric activators include tri-substituted boron, tellurium, aluminum, gallium and indium or mixtures thereof. The three substituent groups are each independently selected from alkyls, alkenyls, halogen, substituted alkyls, aryls, arylhalides, alkoxy and halides. Preferably, the three groups are independently selected from halogen, mono or multicyclic (including halosubstituted) aryls, alkyls, and alkenyl compounds and mixtures thereof, preferred are alkenyl groups having 1 to 20 carbon atoms, alkyl groups having 1 to 20 carbon atoms, alkoxy groups having 1 to 20 carbon atoms and aryl groups having 3 to 20 carbon atoms (including substituted aryls). More preferably, the three groups are alkyls having 1 to 4 carbon groups, phenyl, naphthyl or mixtures thereof. Even more preferably, the three groups are halogenated aryl groups, preferably fluorinated aryl groups. Most preferably, the neutral stoichiometric activator is tris(perfluorophenyl)boron or tris(perfluoronaphthyl)boron.
Ionizing stoichiometric activator compounds may contain an active proton, or some other cation associated with, but not coordinated to, or only loosely coordinated to, the remaining ion of the ionizing compound. Such compounds and the like are described in European publications EP-A-0 570 982, EP-A-0 520 732, EP-A-0 495 375, EP-B1-0 500 944, EP-A-0 277 003 and EP-A-0 277 004, and U.S. Pat.

Ionic catalysts can be prepared by reacting a transition metal compound with one or more neutral Lewis acids, such as B(C6F6)3, which upon reaction with the hydrolyzable ligand (X) of the transition metal compound forms an anion, such as ([B(C6F5)3(X)]−), which stabilizes the cationic transition metal species generated by the reaction. The catalysts can be, and preferably are, prepared with activator components which are ionic compounds or compositions. However preparation of activators utilizing neutral compounds is also contemplated by this invention.
Compounds useful as an activator component in the preparation of the ionic catalyst systems used in the process of this invention comprise a cation, which is preferably a Bronsted acid capable of donating a proton, and a compatible non-coordinating anion which anion is relatively large (sterically bulky), capable of stabilizing the active catalyst species (the Group 4 cation) which is formed when the two compounds are combined and said anion will be sufficiently labile to be displaced by olefinic diolefinic and acetylenically unsaturated substrates or other neutral Lewis bases such as ethers, nitrites and the like. Two classes of compatible non-coordinating anions have been disclosed in EPA 277,003 and EPA 277,004 published 1988: 1) anionic coordination complexes comprising a plurality of lipophilic radicals covalently coordinated to and shielding a central charge-bearing metal or metalloid core, and 2) anions comprising a plurality of boron atoms such as carboranes, metallacarboranes and boranes.
In a preferred embodiment, the stoichiometric activators include a cation and an anion component, and may be represented by the following formula:
(L*-H)d +(Ad−)  (14)
  • wherein L* is an neutral Lewis base;
  • H is hydrogen;
  • (L*-H)+ is a Bronsted acid
  • Ad− is a non-coordinating anion having the charge d−
  • d is an integer from 1 to 3.
The cation component, (L*-H)d + may include Bronsted acids such as protons or protonated Lewis bases or reducible Lewis acids capable of protonating or abstracting a moiety, such as an alkyl or aryl, from the transition metal catalyst compound, resulting in a cationic transition metal species.
The activating cation (L*-H)d − may be a Bronsted acid, capable of donating a proton to the transition metal catalytic precursor resulting in a transition metal cation, including ammoniums, oxoniums, phosphoniums, silyliums, and mixtures thereof, preferably ammoniums of methylamine, aniline, dimethylamine, diethylamine, N-methylaniline, diphenylamine, trimethylamine, triethylamine, N,N-dimethylaniline, methyldiphenylamine, pyridine, p-bromo N,N-dimethylaniline, p-nitro-N,N-dimethylaniline, phosphoniums from triethylphosphine, triphenylphosphine, and diphenylphosphine, oxomiuns from ethers such as dimethyl ether diethyl ether, tetrahydrofuran and dioxane, sulfoniums from thioethers, such as diethyl thioethers and tetrahydrothiophene, and mixtures thereof. The activating cation (L-H)d + may also be a moiety such as silver, tropylium, carbeniums, ferroceniums and mixtures, preferably carboniums and ferroceniums. Most preferably (L*-H)d + is triphenyl carbonium.
The anion component Ad− include those having the formula [Mk+Qn]d− wherein k is an integer from 1 to 3; n is an integer from 2–6; n−k=d; M is an element selected from Group 13 of the Periodic Table of the Elements, preferably boron or aluminum, and Q is independently a hydride, bridged or unbridged dialkylamido, halide, alkoxide, aryloxide, hydrocarbyl, substituted hydrocarbyl, halocarbyl, substituted halocarbyl, and halosubstituted-hydrocarbyl radicals, said Q having up to 20 carbon atoms with the proviso that not more than one Q group is a halide. Preferably, each Q is a fluorinated hydrocarbyl group having 1 to 20 carbon atoms, more preferably each Q is a fluorinated aryl group, and most preferably each Q is a pentafluoryl aryl group. Examples of suitable Ad− also include diboron compounds as disclosed in U.S. Pat. No. 5,447,895, which is fully incorporated herein by reference.

In one embodiment, an activation method using ionizing ionic compounds not containing an active proton but capable of producing a ligand metallocene catalyst cation and their non-coordinating anion are also contemplated, and are described in EP-A-0 426 637, EP-A-0 573 403 and U.S. Pat. No. 5,387,568, which are all herein incorporated by reference.
Invention catalyst precursors can also be activated with cocatalysts or activators that comprise non-coordinating anions containing metalloid-free cyclopentadienide ions. These are described in U.S. Patent Publication 2002/0058765 A1, published on 16 May 2002.
The term “non-coordinating anion” (NCA) means an anion which either does not coordinate to said cation or which is only weakly coordinated to said cation thereby remaining sufficiently labile to be displaced by a neutral Lewis base. “Compatible” non-coordinating anions are those which are not degraded to neutrality when the initially formed complex decomposes. Further, the anion will not transfer an anionic substituent or fragment to the cation so as to cause it to form a neutral four coordinate metallocene compound and a neutral by-product from the anion. Non-coordinating anions useful in accordance with this invention are those that are compatible, stabilize the metallocene cation in the sense of balancing its ionic charge at +1, yet retain sufficient lability to permit displacement by an ethylenically or acetylenically unsaturated monomer during polymerization. These types of cocatalysts sometimes use tri-isobutyl aluminum or tri-octyl aluminum as a scavenger.
Invention process also can employ cocatalyst compounds or activator compounds that are initially neutral Lewis acids but form a cationic metal complex and a noncoordinating anion, or a zwitterionic complex upon reaction with the invention compounds. For example, tris(pentafluorophenyl) boron or aluminum act to abstract a hydrocarbyl or hydride ligand to yield an invention cationic metal complex and stabilizing noncoordinating anion, see EP-A-0 427 697 and EP-A-0 520 732 for illustrations of analogous Group-4 metallocene compounds. Also, see the methods and compounds of EP-A-0 495 375. For formation of zwitterionic complexes using analogous Group 4 compounds, see U.S. Pat. Nos. 5,624,878; 5,486,632; and 5,527,929.
When the cations of noncoordinating anion precursors are Bronsted acids such as protons or protonated Lewis bases (excluding water), or reducible Lewis acids such as ferrocenium or silver cations, or alkali or alkaline earth metal cations such as those of sodium, magnesium or lithium, the catalyst-precursor-to-activator molar ratio may be any ratio. Combinations of the described activator compounds may also be used for activation. For example, tris(perfluorophenyl) boron can be used with methylalumoxane.
When an ionic activator is used, the catalyst-precursor-to-activator molar ratio is from 1:10 to 1.2:1; 1:10 to 10:1; 1:10 to 2:1; 1:10 to 3:1; 1:10 to 5:1; 1:2 to 1.2:1; 1:2 to 10:1; 1:2 to 2:1; 1:2 to 3:1; 1:2 to 5:1; 1:3 to 1.2:1; 1:3 to 10:1; 1:3 to 2:1; 1:3 to 3:1; 1:3 to 5:1; 1:5 to 1.2:1; 1:5 to 10:1; 1:5 to 2:1; 1:5 to 3:1; 1:5 to 5:1.
The catalyst-precursor-to-alkylating-agent molar ratio is from 1:100 to 100:1; 1:50 to 50:1; 1:10 to 10:1; 1:10 to 2:1; 1:10 to 25:1; 1:10 to 3:1; 1:10 to 5:1; 1:2 to 10:1; 1:2 to 2:1; 1:2 to 25:1; 1:2 to 3:1; 1:2 to 5:1; 1:25 to 10:1; 1:25 to 2:1; 1:25 to 25:1; 1:25 to 3:1; 1:25 to 5:1; 1:3 to 10:1; 1:3 to 2:1; 1:3 to 25:1; 1:3 to 3:1; 1:3 to 5:1; 1:5 to 10:1; 1:5 to 2:1; 1:5 to 25:1; 1:5 to 3:1; 1:5 to 5:1.

    Mixed Catalysts:
Mixed catalyst systems can also be used, for example, the invention catalyst can be used in conjunction with a second catalyst in the same reactor or in a series of reactors where the invention catalyst produces ethylene oligomers and the second catalyst incorporates these oligomers into a polymer backbone as a copolymer with ethylene.
Invention polymerization catalyst systems can comprise additional olefin polymerization catalysts. These additional olefin polymerization catalysts are any of those well known in the art to catalyze the olefin to polyolefin reaction. Some invention catalysts systems include Group-4–6 metallocenes as additional olefin polymerization catalysts. Metallocenes include (un)bridged compounds containing one (mono(cyclopentadienyl) metallocenes) or two (bis(cyclopentadienyl) metallocenes) (un)substituted cyclopentadienyl ligand(s). In bridged metallocenes, a single, cyclopentadienyl ligand connects to a heteroatom ligand with both coordinating to the metal center, or two cyclopentadienyl ligands connect together with both cyclopentadienyl ligands coordinating to the metal center. Typical catalysts and their precursors are well known in the art. Suitable description appears in the patent literature, for example U.S. Pat. Nos. 4,871,705, 4,937,299, 5,324,800, EP-A-0418044, EP-A-0591756, WO-A-92/00333 and WO-A-94/01471. Some embodiments select the metallocene compounds from mono- or bis-cyclopentadienyl-substituted, Group-4, -5, and -6 metals in which cyclopentadienyls are (un)substituted with one or more groups or are bridged to each other or to a metal-coordinated heteroatom. Some embodiments select similar metallocene compounds except they are not necessarily bridged to each other or to a metal-coordinated heteroatom. See U.S. Pat. Nos. 5,278,264 and 5,304,614.
Some invention catalysts systems include the following additional olefin polymerization catalysts. Metallocene compounds suitable for linear polyethylene or ethylene-containing copolymer production (where copolymer means comprising at least two different monomers) are essentially those disclosed in WO-A-92/00333, WO 97/44370 and U.S. Pat. Nos. 5,001,205, 5,057,475, 5,198,401, 5,304,614, 5,308,816 and 5,324,800. Selection of metallocene compounds for isotactic or syndiotactic polypropylene blend production, and their syntheses, are well-known in the patent and academic literature, e.g. Journal of Organometallic Chemistry 369, 359–370 (1989). Typically, those catalysts are stereorigid, asymmetric, chiral, or bridged-chiral metallocenes. Invention activators are suited for activating these types of catalyst precursors.
Likewise, some invention catalysts systems include the following additional olefin polymerization catalysts: monocyclopentadienyl metallocenes with Group-15 or -16 heteroatoms connected, through a bridging group, to a cyclopentadienyl-ligand ring carbon. Both the cyclopentadienyl Cp-ligand and the heteroatom connect to a transition metal. Some embodiments select a Group-4 transition metal. Additionally, unbridged monocyclopentadienyl, heteroatom-containing Group-4 components of WO 97/22639 will function with this invention. Moreover, transition metal systems with high-oxidation-state, Group-5–10 transition-metal centers are known and can serve as the additional olefin polymerization catalysts with invention catalyst systems.
Invention catalyst systems can use non-cyclopentadienyl, Group-4–5 precursor compounds as the additional olefin polymerization catalysts. Non-cyclopentadienyl, Group-4–5 precursor compounds are activable to stable, discrete cationic complexes include those containing, chelating, diamide ligands, such as described in U.S. Pat. No. 5,318,935 and “Conformationally Rigid Diamide Complexes: Synthesis and Structure of Tantalum (III) Alkyne Derivatives”, D. H. McConville, et al, Organometallics 1995, 14, 3154–3156. U.S. Pat. No. 5,318,935 describes bridged and unbridged, bis-amido catalyst compounds of Group-4 metals capable of α-olefins polymerization. Bridged bis(arylamido) Group-4 compounds for olefin polymerization are described by D. H. McConville, et al., in Organometallics 1995, 14, 5478–5480. Synthetic methods and compound characterization are presented. Further work appearing in D. H. McConville, et al, Macromolecules 1996, 29, 5241–5243, describes bridged bis(arylamido) Group-4 compounds that are polymerization catalysts for 1-hexene. Additional invention-suitable transition-metal compounds include those described in WO 96/40805. Cationic Group-3- or Lanthanide olefin polymerization complexes are disclosed in copending U.S. application Ser. No. 09/408,050, filed 29 Sep. 1999, and its equivalent PCT/US99/22690. A monoanionic bidentate ligand and two monoanionic ligands stabilize those catalyst precursors; they are activable with this invention” ionic cocatalysts. Other suitable Group-4–5 non-metallocene catalysts are bimetallocyclic catalyst compounds comprising two independently selected Group-4–5 metal atoms directly linked through two bridging groups to form cyclic compounds.
Invention catalyst systems can use other transition metal catalyst precursors that have a 2+ oxidation state as the additional olefin polymerization catalyst. Typical Ni2+ and Pd2+ complexes are diimines, see “New Pd(II)- and Ni(II)- Based Catalysts for Polymerization of Ethylene and α-Olefins”, M. Brookhart, et al, J. Am. Chem. Soc., 1995, 117, 6414–6415, WO 96/23010 and WO 97/02298. See additionally the related bis(imino) Group-8 and -9 organometallic compounds described by V. C. Gibson and others in “Novel olefin polymerization catalysts based on iron and cobalt”, Chem. Commun., 849–850, 1998.
For a review of other potential catalysts used in combination or series with the invention catalysts, see S. D. Ittel and L. K. Johnson, Chem. Rev. 2000, 1000, 1169 and V. C. Gibson and S. K. Spitzmesser, Chem. Rev. 2003, 103, 283.
Supports:
The transition metal catalyst components described herein may be supported. For example, one or more transition metal catalyst components and/or one or more activators may be deposited on, contacted with, vaporized with, bonded to, or incorporated within, adsorbed or absorbed in, or on, one or more supports or carriers.
The support material may be any of the conventional support materials. Preferably the support material is a porous support material, for example, talc, inorganic oxides and inorganic chlorides. Other support materials include resinous support materials such as polystyrene, functionalized or crosslinked organic supports, such as polystyrene divinyl benzene polyolefins or polymeric compounds, zeolites, clays, or any other organic or inorganic support material and the like, or mixtures thereof.
Preferred support materials are inorganic oxides that include those Group 2, 3, 4, 5, 13 or 14 metal oxides. Preferred supports include silica, which may or may not be dehydrated, fumed silica, alumina (WO 99/60033), silica-alumina and mixtures thereof. Other useful supports include magnesia, titania, zirconia, magnesium chloride (U.S. Pat. No. 5,965,477), montmorillonite (European Patent EP-B1 0 511 665), phyllosilicate, zeolites, talc, clays (U.S. Pat. No. 6,034,187) and the like. Also, combinations of these support materials may be used, for example, silica-chromium, silica-alumina, silica-titania and the like. Additional support materials may include those porous acrylic polymers described in EP 0 767 184 B1, which is incorporated herein by reference. Other support materials include nanocomposites as described in PCT WO 99/47598, aerogels as described in WO 99/48605, spherulites as described in U.S. Pat. No. 5,972,510 and polymeric beads as described in WO 99/50311, which are all herein incorporated by reference. Lewis acidic materials such as montmorillonite and similar clays may also serve as a support. In this case, the support can optionally double as the activator component. But additional activator may also be used.
It is preferred that the support material, most preferably an inorganic oxide, has a surface area in the range of from about 10 to about 700 m2/g, pore volume in the range of from about 0.1 to about 4.0 cc/g and average particle size in the range of from about 5 to about 500 μm. More preferably, the surface area of the support material is in the range of from about 50 to about 500 m2/g, pore volume of from about 0.5 to about 3.5 cc/g and average particle size of from about 10 to about 200 μm. Most preferably the surface area of the support material is in the range is from about 100 to about 400 m2/g, pore volume from about 0.8 to about 3.0 cc/g and average particle size is from about 5 to about 100 μm. The average pore size of the carrier useful in the invention typically has pore size in the range of from 10 to 1000 Å, preferably 50 to about 500 Å, and most preferably 75 to about 350 Å.
As is known in the art, the catalysts may also be supported together on one inert support, or the catalysts may be independently placed on two inert supports and subsequently mixed. Of the two methods, the former is preferred.
In another embodiment the support may comprise one or more types of support material which may be treated differently. For example one could use two different silicas that had different pore volumes or had been calcined at different temperatures. Likewise one could use a silica that had been treated with a scavenger or other additive and a silica that had not.
Supported transition metal catalyst compounds, activators, or catalyst systems may be prepared by placing the support material (which may be pre-treated, such as calcined or functionalized) and one or more catalyst compounds, or one or more activators, or both activators and catalyst compounds in a diluent, typically a solvent, and them removing the diluent or solvent. The volume of the liquid may be from 0.5 to 20 time the pore volume of the support or more. Certain embodiments, however, use 1 to 3 times the pore volume of the support.
Typically the instant supported catalyst systems may be prepared by any method effective to support other coordination catalyst systems, effective meaning that the catalyst so prepared can be used for oligomerizing or polymerizing monomers in a heterogeneous process. The catalyst precursor, activator, suitable diluent, and support may be added in any order or simultaneously. In one invention embodiment, the activator, dissolved in an appropriate solvent such as toluene is stirred with the support material for 1 minute to 10 hours. The total volume of the activation solution may be greater than the pore volume of the support, but some embodiments limit the total solution volume below that needed to form a gel or slurry (about 100–200% of the pore volume). In some embodiments the volume of the solution is limited to between 1 and 5 times the pore volume of the support, typically between 1.5 and 3. The mixture is optionally heated to 30–200° C. during this time. The catalyst can be added to this mixture as a solid, if a suitable solvent is employed in the previous step, or as a solution. Or alternatively, this mixture can be filtered, and the resulting solid mixed with a catalyst precursor solution. Similarly, the mixture may be vacuum dried and mixed with a catalyst precursor solution. The resulting catalyst mixture is then stirred for 1 minute to 10 hours, and the catalyst is either filtered from the solution and vacuum dried, or vacuum or evaporation alone removes the solvent.
In another invention embodiment, the catalyst precursor and activator are combined in solvent to form a solution. The support is then added to this solution and the mixture is stirred for 1 minute to 10 hours. The total volume of this solution may be greater than the pore volume of the support, but some embodiments limit the total solution volume below that needed to form a gel or slurry (about 100–200% pore volume). In some embodiments the volume of the solution is limited to between 1 and 5 times the pore volume of the support, typically between 1.5 and 3. The residual solvent is then removed, typically under vacuum, typically at ambient temperature and over 10–16 hours. But greater or lesser times are possible.
The catalyst precursor may also be supported in the absence of the activator, in which case the activator is added to the liquid phase of a slurry process. For example, a solution of catalyst precursor is mixed with a support material for a period of up to 10 hours. The resulting catalyst precursor mixture is then filtered from the solution and dried under vacuum, or vacuum or evaporation alone removes the solvent. The total volume of the catalyst precursor solution may be greater than the pore volume of the support, but some embodiments limit the total solution volume below that needed to form a gel or slurry (about 100–200% of the pore volume). In some embodiments the volume of the solution is limited to between 1 and 5 times the pore volume of the support, typically between 1.5 and 3. Additionally, two or more different catalyst precursors may be placed on the same support using any of the support methods disclosed above. Likewise, two or more activators may be placed on the same support.
As well know in the art, the support material may be pretreated by any number of methods. For example, inorganic oxides may be calcined, and/or chemically treated with dehydroxylating agents such as aluminum alkyls and the like.
Some embodiments select the carrier of invention catalysts to have a surface area of 10–700 m2/g, or pore volume of 0.1–4.0 cc/g, and average particle size from 10–500 microns. But greater or lesser values may also be used.
The transition metal catalyst compounds may generally be deposited on the support at a loading level of 10–100 micromoles of catalyst precursor per gram of solid support; alternately from 20–80 micromoles of catalyst precursor per gram of solid support; or from 40–60 micromoles of catalyst precursor per gram of support. But greater or lesser values may be used. Some embodiments select greater or lesser values, but require that the total amount of solid catalyst precursor does not exceed the support's pore volume.
Additionally, oxidizing agents may be added to the supported or unsupported catalyst as described in WO 01/68725.
In another embodiment the activator is bound to the support prior to combination with the transition metal catalyst compound. For more information on support bound activators, please see U.S. Pat. No. 5,643,847, U.S. Pat. No. 5,972,823, EP 0 775 164 B1, WO 00/4059 A1, WO 95/9578 A1.
Oligomerization or Polymerization Process
The catalyst compositions described above may be used to oligomerize or polymerize any unsaturated monomer, however they are preferably used to oligomerize olefins, typically alpha-olefins. In the instant oligomerization processes, the process temperature may be −100° C. to 300° C., −20° C. to 200° C., or 0° C. to 150° C. Some embodiments select oligomerization pressures (gauge) from 0 kPa–35 MPa or 500 kPa–15 MPa. A preferred feedstock for the oligomerization process is the alpha-olefin, ethylene. But other alpha-olefins, including but not limited to propylene and 1-butene, may also be used alone or combined with ethylene. Preferred alpha-olefins include any C2 to C40 alpha-olefin, preferably and C2 to C20 alpha-olefin, preferably any C2 to C12 alpha-olefin, preferably ethylene, propylene, and butene, most preferably ethylene. Dienes may be used in the processes described herein, preferably alpha, omega-dienes are used alone or in combination with mono-alpha olefins.
Preferred oligomerization processes may be run in the presence of various liquids, particularly aprotic organic liquids. Preferably the homogeneous catalyst system, ethylene, alpha-olefins, and product are soluble in these liquids. A supported (heterogeneous) catalyst system may also be used, but will form a slurry rather than a solution. Suitable liquids for both homo- and heterogeneous catalyst systems, include alkanes, alkenes, cycloalkanes, selected halogenated hydrocarbons, aromatic hydrocarbons, and in some cases, hydrofluorocarbons. Useful solvents specifically include hexane, toluene, cyclohexane, and benzene.
The instant invention may also be used to obtain mixtures of olefins containing desirable numbers of carbon atoms. Factor K from the Schulz-Flory theory (see for instance B. Elvers, et al., Ed. Ullmann's Encyclopedia of Industrial Chemistry, Vol. A13, VCH Verlagsgesellschaft mbH, Weinheim, 1989, p. 243–247 and 275–276) serves as a measure of these olefins' molecular weights. From this theory, K=n(Cn+2 olefin)/n(Cn olefin), where n(Cn olefin) is the number of moles of olefin containing n carbon atoms, and n(Cn+2 olefin) is the number of moles of olefin containing n+2 carbon atoms, or in other words the next higher oligomer of Cn olefin. From this can be determined the weight (mass) fractions of the various olefins in the resulting product. The ability to vary this factor provides the ability to choose the then-desired olefins.
Invention-made olefins may be further polymerized with other olefins to form more oligomers or even form homopolymers and copolymers of the alpha olefins produced. These polymers may be made by a number of known methods, such as Ziegler-Natta-type polymerization, metallocene catalyzed polymerization, and other methods, see for instance WO 96/23010, see for instance Angew. Chem., Int. Ed. Engl., vol. 34, p. 1143–1170 (1995); European Patent Application, 416,815; and U.S. Pat. No. 5,198,401 for information about metallocene-type catalysts, and J. Boor Jr., Ziegler-Natta Catalysts and Polymerizations, Academic Press, New York, 1979 and G. Allen, et al., Ed., Comprehensive Polymer Science, Vol. 4, Pergamon Press, Oxford, 1989, pp. 1–108, 409–412 and 533–584, for information about Ziegler-Natta-type catalysts, and H. Mark, et al., Ed., Encyclopedia of Polymer Science and Engineering, Vol. 6, John Wiley & Sons, New York, 1992, p. 383–522, for information about polyethylene.
Preferred oligomerization processes include oligomerizing ethylene to C4–C26 linear alpha-olefins.
Oligomers produced herein may be used as polyolefin feed stocks. They may be used as a mixture of olefins alone, as a mixture of olefins added to other olefins, or they may be separated into fractions and then used alone or in combination with other olefins to form polyolefins. Additionally, alpha-olefins produced herein may be converted to alcohols by known processes, these alcohols being useful for a variety of applications such as intermediates for detergents or plasticizers. Typical processes for the conversion of alpha-olefins to alcohols include, but are not limited to the oxo process followed by hydrogenation, or by a modified, single-step oxo process (the modified Shell process), see for instance B. Elvers, et al., Ed., Ullmann's Encyclopedia of Chemical Technology, 5th Ed., Vol. A18, VCH Verlagsgesellschaft mbH, Weinheim, 1991, p. 321–327.

Oligomerizations
The reagents used in the oligomerization tests were Ethylene Grade 3.5 (supplied from BOC) and methylaluminoxane (MAO, 10% wt solution in toluene, supplied by Aldrich). GC measurements were obtained using an HP 5890 chromatogram [Column type SGE HT-5 (aluminum clad fused silica capillary); Column length 12 m; Column internal diameter 0.53 mm; Initial column temperature 55 C] with a flame ionization detector [FID (440 C)].
Example 13
Schlenk Tube Oligomerization
The complexes 3a and 3b made in Examples 7 and 8 above were dissolved or suspended in toluene (40 cm3) and MAO introduced. The tube was purged with ethylene and the contents stirred under one bar ethylene at 25° C. for the duration of the oligomerization. After half an hour the oligomerization was terminated by the addition of aqueous hydrogen chloride. The aqueous phase was separated and washed with toluene (2×25 ml) and all organic layers combined and dried over anhydrous magnesium sulfate. The solutions were prepared for quantitative GC analysis by diluting the organic phases to 100 ml with toluene in a volumetric flask and adding 1-heptadecene (50 μl) as an internal standard. The runs are summarized in Table 2. FIG. 5 shows the Schulz-Flory distribution for runs 1 and 3 using pre-catalysts, 3a and 3c, respectively. FIG. 6 shows the oligomer distribution of oligomer fractions versus carbon number for runs 2 and 4 using pre-catalysts 3b and 3d, respectively.
